SPECIFICATION forming part of Letters PatentNo. 434,429, dated August.19, 1890.

Application filed June 13, 1890. Serial No. 355,301. (No model.)

To all whom it may concern..-

Be it known that I, IIARRYBARRINGER Cox, of Hartford, in the county ofHartford and State of'Conuectieut, have invented certain new and usefulImprovements in 'lhermo- Electric Generators; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

This invention relates to certain improvements in thermo-electricgenerators.

In my application, Serial No. 334,7 43, dated December 23, 1859, forLetters Patent for an improvement in thermo-electric generators, asingle conductor or radiator within the circuit is shown and describedto produce a fall in thermic potential. By experiment it has been foundthat a series of such conductors or radiators within the circuit producean improved result; and this invention consists in a series ofconductors or radiators in thermoelectric couples placed within thecircuit of the same to produce a fall in thermic potential.

Referring to the accompanying drawings, Figure 1 illustrates inelevation a series of thermo-eouples each provided with two radiators orconductors. Fig. 2 illustrates the same provided with three radiators orconductors. Fig. I) illustates the sameprovided with four radiators orconductors.

Each thermo-eouple consists of the two unlike elements ab, composed ofunlike metals joined together in a suitable manner. Of course in forminga pile any number of these.

couples are employed, the strips a extending from one end of one largeelement b to the opposite end of the next adjoining element 1), and heatis applied from any suitable source to the junctions at correspondingends of the elements. The opposite corresponding junctions are to bekept at as low temperature as possible.

A series of conducting or radiating strips (1, of good conducting metal,are electrically connected with and extend from each large element 1),between the hot and cold junctions thereof, toward the source of cold.The object of the series of radiators and conductors is to produce afall in thermic potential in the circuit.

\Vhat I claim is- 1. In th'ermo-clectric couples, a series of radiatorsor conductors placed within the circuit of the couple to produce a fallin thermic potential, substantially as described.

2. In a thermo-electric generator, a series of radiators within thecircuit of each couple to produce a fall in thermic potential,substantially as described. v

A thermo-couple having a series of conductors or radiators in thecircuit thereof and extending therefrom between the hot and coldjunctions thereof, substantially as vdeeribed.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

HARRY BARRINGER COX.
